| 中文摘要 | 鎘為土壤中可被植物吸收之一種重金屬,惟鎘可能會影響植物必需元素的吸收。因此,本研究探討水稻在鎘處理下鐵濃度之變化。水稻處理5μM氯化鎘時,鎘濃度會增加,但根部與地上部的鐵濃度會減少。此外,鎘處理時會增加水稻根部OsIRT1基因的表現。外加多量之Fe-citrate會降低水稻幼苗中鎘的濃度與鎘的毒害。本研究之證據顯示改善水稻幼苗中Fe濃度,可降低鎘之毒害。 |
| 英文摘要 | Cadmium (Cd) is one of the most bioavailable heavy metal in soils. Cadmium may interfere with the uptake of essential elements. Thus, in this study, we investigated the changes in iron (Fe) concentration in Cd-treated rice (Oryza sativa L.) seedlings. On treatment with 5 μM CdCl2, Cd concentration increased, whereas Fe concentration decreased in both shoots and roots of rice seedlings. Moreover, Cd treatment resulted in an induction of OsIRT1 transcript in roots of rice seedlings. Exogenous addition of excess Fe-citrate decreased Cd concentration and Cd toxicity of rice seedlings. Evidence presented in this study suggests that the improvement of Fe status is able to reduce toxicity of rice seedlings to CdCl2. |
